I have an older Autohelm 1000 and apparently have a loose connection at the cord. The unit cuts out, but when I play with the cord where it enters the housing, it works. I want to open up the case so I can re-do the connection, however, the 6 screws that hold the case together have a completely unique head. Does anyone know what kind of screwdriver/nut driver is needed to engage these screwheads?

Visit the Raymarine site and search their users'' help forum; the answer may be there. If not, you can post your query and they will answer it. Another (perhaps parallel) query to their general email address might work, too.

I think Raymarine has an excellent Q&A Forum for these kinds of things. Reading some of the problems that are addressed and using the functional search engine, I''m left wondering why this isn''t more often seen.

If memory serves, theyíre either T10 or T15 Torx heads. If you have to ask that question, Iíd ask if you have the expertise to go inside of that thing with out doing further damage. Thereís quite a bit of sensitive parts and circuitry involved as specially around the compass head and that red trim around itís midships is actually a seal which can be a bit of a bother to properly put back in place. The plastic in those older ones can get quite brittle and they donít take too kindly to flexing or being forced. Iíd recommend taking it to someone with a background in repairing electrical and mechanical items. It may not be rocket science but itís $400 in the trashcan if you screw it up!

The Pirate is right unfortunately. I work on all sorts of electronics and have experience with that unit. If there is anyway to not open the controller, don''t. The boards are connected together U.K. style and very prone to failure. The dodge switch will fall out, the O-ring will need to be replaced, they are tough to get back together correctly and you will most probably end up with an intermittent new problem. I wasted 6 hours on one of those things with a similar problem. If you must crack it open and need help, drop me a note.
